WHAT IS THE DALIC TECHNOLOGY ?

Dalic is a technology for selective electrochemical metallizing, which is achieved without immersion of the part. An anodic tool impregnated with the metalliing solution is placed ont the area to plate. Under the action of current, the metal is plated on the part. It is the DALIC brushplating process (photo 1). Latest development of DALIC R & D, the Dalistick is a no-leak tool for surface finishing in thin layers (photo 2).


ADVANTAGES OF THE PROCESS :

  • very selective plating : only the exposed or damaged area is treated, with limited masking,
  • fast plating due to high current density : the downtime is reduced to minimum,
  • plating thickness is controlled and no further machining is generally required,
  • in-situ application is possible with minimum dismounting,
  • environment friendly process due to small quantity of plating solutions,
  • cold plating process, therefore no stress for the base material.


APPLICATIONS OF THE PROCESS

  • protection against atmospheric and galvanic corrosion
  • CAA, SAA et PAA anodizing
    Plating of Cadmium LHE and other metals and alloys.
  • rebuilding the part to its initial specs,
  • improving surface properties : anti-friction, gliding, hardness,
  • improve resistance to abrasion, wear, erosion and antisticking,
  • improvement of electrical properties,
  • repair of damagesn scratches, holes.
